Hi,
I got a Oops when the hard drive was COMPLETELY full using a ext4 fs.
After it, any command on the directory where the last write should have
occurred freezes, while any other directory behave just fine.
If this email is not relevant for you, please point me what to do.

I guess this patch will be ignored. I will drop it then.
Thanks for the discussion.

Hi Anand,
I'm using this frequencies on the board since 3 years, without any stability
issues. The kind of worklaod used is intensive CPU-bound benchmarks running
for 20 mins at least in order to stress the system, I'm studying schedulability
under high thermal constraints.
So, I would say these
Hi,
This patch can be dropped, as it needs more work.
In fact, the interrupts seems to be wrong. The interrupts suggested by
Anand Moon gave the same following results.
export CCI_DEV=CCI_400
export OMP_NUM_THREADS=2
sudo --preserve-env ./perf stat -a \
-e armv7_cortex_a7/config=0x11,name=a7_c
E_LEVEL_HIGH,
I will do a v2 for this. Don't you think that the doc at
Documentation/devicetree/bindings/arm/cci.txt should use this too?

If a trip of type critical is defined before any trip of passive
or active type, power_allocator governor will not switch on.

Hi everybody,
Is DVFS for memory bus really working on Odroid XU3/4 board?
Using a simple microbenchmark that is doing only memory accesses, memory DVFS
seems to not working properly:
The microbenchmark is doing pointer chasing by following index in an array.
Indices in the array are set to follo
ontinue experimenting with irq mode, so I would like to
still have the code in the driver.
Regards,
Lukasz

Hi,
I'm trying to add pmu support for CCI400 on an Odroid-XU3/4.
Following
https://www.kernel.org/doc/Documentation/devicetree/bindings/arm/cci.txt,
and other dtsi, I end up with this patch:
diff --git a/arch/arm/boot/dts/exynos5420.dtsi
b/arch/arm/boot/dts/exynos5420.dtsi
index f4e8c5823bc2..8
Add device tree entries for PMU of ARM CCI-400.
$ sudo ./perf stat -a -C 0 -e CCI_400/config=0xff,name=cycles/ sleep 1
Performance counter stats for 'system wide':
420,303,619 cycles

Tested on Odroid-xu3 and 4.

Many thanks, it seems to work.

This patch change usage of printk to their pr_* equivalent.
Note, pr_debug(...) will not be emitted unless DEBUG is defined or

ical path.
Maybe memtester is doing writes and devfreq heuristic uses only write info?
